Home › Developer Tools › JSON to Excel Converter
Paste a JSON array of objects and download a genuine Excel .xlsx workbook. The conversion runs in your browser using the SheetJS library; your JSON itself is never uploaded.
Each object becomes a row and each key a column — the same shape as our JSON to CSV tool, but saved as a native Excel file so formatting, types and sheet structure survive. If the Excel library cannot load (for example on a network that blocks CDNs), the tool will tell you — the JSON to CSV converter is the built-in fallback, and Excel opens CSV files directly.
An array of objects works best. A single object becomes a one-row sheet.
No. Only the Excel library file is downloaded; your JSON stays in the page.
